If you do split the case, you can do anything you want. You could get a more aggressive cam. Make sure you mark the lifters and return them to the same position IF you re-use the cam and lifters. ALWAYS replace them both if you replace the cam.

You can just get the case opened for the 94mm barrels, since you're splitting it. If the oil pickup is loose, you can clean up all the oil and JB Weld it in place, and peen the case with a ball-peen hammer around the pickup tube. Sometimes the case has a sloppy fit around the oil pump, and a shmeer of Permatex Aviation case sealant around the pump suction hole might be all you need.

When you get the heads flycut for the 94 barrels, pay attention to two things: parallel of cylinder sealing areas and combustion chamber volume. You may want to reduce the chamber size and up the compression depending on the cam/lifter combo you have. Compression ratio of 9:1 static would be a MINIMUM for me, especially since you have EFI and it will never go lean.

I'll post photos later of the 94mm barrel spigot uncut and cut, maybe that will help you make your decision there.

Above all, take your time(I know you do!), mock it up a few times, and have fun.
